Fundamental time period of bridge pier

I want to calculate fundamental time period (eigen value method, using command MODAL CALCULATION REQUESTED) of  bridge pier in staad pro using lumped mass in long & Trans direction as per IRC 6 & IRC SP 114.

I am enclosing the details . I think there are some mistakes in my models. But I am not able to figure it out. Would any one be kind enough to check the models7140.Fundamental Time Period Trans Direction.std4760.Fundamental Time Period Long Direction.std?

Details are:

Span of superstructure: 27 m simply supported

Total DL of one span: 523 T

SIDL (Crash barrier + Wearing Coat) of one span: (54 T + 52 T)
